imagine: pilot trial of a digital group intervention to prevent perinatal depression

Conditions: Depression During Pregnancy; Depression, Postpartum

Summary: the goal of this clinical trial is to evaluate if a digital group intervention (named imagine) can prevent depression in perinatal populations. the main questions it aims to answer are: does imagine engage cognitive behavioral therapy targets? does imagine lead to lower depression scores? is imagine acceptable, appropriate, usable and feasible? participants will be randomized to either participate in an imagine group for 12 weeks or receive standard of care. participants will respond to questionnaires at enrollment and study visits at 12 and 24 weeks after enrollment.

perinatal depression affects an estimated 13% of pregnant people in the us. while effective interventions exist to prevent perinatal depression, access to facility-based in-person interventions is limited. this proposal will refine a digital group adaptation of an evidence-based prevention intervention, and evaluate its preliminary effectiveness and implementation outcomes through a pilot randomized controlled trial. the proposal consists of 3 specific aims: aim 1. using human-centered design, refine the imagine intervention for implementation within perinatal mental health services in washington state. building off existing imagine intervention materials, we will conduct qualitative interviews and focus groups with perinatal people, service providers, administrators, and payers to refine: 1. imagine intervention design to meet the needs of perinatal clients age 16-35. components to be optimized include message frequency, balance of synchronous and asynchronous content, and group composition. 2. imagine implementation protocols and materials to support delivery by our implementation partner. hypothesis: combined synchronous and asynchronous content and delivery compliant with billable health services will be preferred. aim 2. determine imagine's preliminary effectiveness engaging cbt targets and preventing depression. a pilot rct will be conducted comparing imagine (as optimized in aim 1) delivered in english or spanish vs. treatment as usual, among 100 perinatal participants (pregnant or ≤6 months postpartum) with one or more risk factors for perinatal depression (as defined by uspstf) and no current major depression. participants will be recruited from our partner organization's clients. we will compare longitudinal change in depression symptoms and engagement of target mechanisms (negative mood regulation, perceived stress, and perceived social support) between arms at enrollment, 12- and 24-weeks post-enrollment. exploratory analyses will assess effect modification by participant age, race/ethnicity, pregnancy status, and language. hypothesis: imagine will lead to moderate reduction in depression symptoms, with effect size similar to mb. aim 3. determine imagine's preliminary implementation outcomes (acceptability, appropriateness, usability, and feasibility) among client, provider, administrator, and payer stakeholders. acceptability, appropriateness and usability among rct participants will be assessed based on quantitative questionnaires, engagement in imagine, and qualitative interviews. provider, administrator, and payer acceptability, feasibility, and appropriateness will be determined through group discussion of imagine rct process indicators. we will explore client and contextual determinants of implementation outcomes.
